1. A lamination apparatus for a secondary battery, which is configured to thermally bond an electrode assembly in which electrodes and separators are alternately stacked, the lamination apparatus comprising:
a transfer member to transfer the electrode assembly;
a support member to support each of top and bottom surfaces of the electrode assembly transferred by the transfer member, the support member including a metal having thermal conductivity;
a heating member disposed outside the support member to heat the electrode assembly supported by the support member, the heating member comprising opposing heaters having platen pressing surfaces respectively disposed outside the support member and configured to heat the electrode assembly supported by the support member and to be moved in a direction towards or away from the electrode assembly; and
a moving member to move the heating member in the direction towards or away from the electrode assembly,
wherein the moving member moves the heating member in the direction away from the electrode assembly to prevent the electrode assembly from being heated by the heating member when the transfer member is stopped,
wherein the support member comprises opposing metal plates having the thermal conductivity to support each of the top and bottom surfaces of the electrode assembly transferred by the transfer member,
wherein the support member further comprises a heat-resistant plate disposed on an inner surface of each of the opposing metal plates on which the electrode assembly is supported, and
wherein the opposing metal plates include an opening groove in an outer surface thereof, which does not face the electrode assembly.
